It should more or less bolt in. You will need the complete fuel system from the other car, which includes the 2 stage fuel pump and the ECM, wiring harness etc. to make everything work. You'll need to figure out a way to retain the boost gauge for the dash readout. Keep engine and transmission from the other car together as the supercharged one is a heavy duty version required to take the extra horsepower of the supercharged engine. Check part numbers to be sure, but the front axle shafts may be specific to the supercharged car as well.
